Hi. I'd liek to know wif you can put a pdf and a mp3 at the same time, such as reading a book while listening to it's audio. Thanks.

For the 604/504, while music is playing use the <MENU> the <OK> buttons to select Home. Go to the Browser folder (where you should store your PDF's) and select a file for viewing. These as method works for Photo folder to view pictures of stup a slide show while listining to music.
